11.SEGMENT INFORMATION
image_1.jpgOur Chief Operating Decision Maker (“CODM”), our President and CEO, uses Adjusted EBITDA as the basis for evaluating the performance of, and allocating resources to, our operating segments. The CODM uses Adjusted EBITDA to ensure that resources, including capital, are allocated strategically to support our strategy.
